Description

Technical Field

[0001] This invention belongs to the field of tire design technology, specifically relating to a method and system for automatically arranging and inserting studs in tire tread patterns. Background Technology

[0002] In the current snow tire production process, design engineers need to manually add studs one by one to models with various pitches. After the tire is assembled, the total number of studs in a specific area must be calculated. If this number fails to meet the relevant regulatory standards, engineers have to manually readjust the specific positions of the studs on each model. As tire tread designs become increasingly complex, and with strict regulations limiting the number of studs, this manual stud arrangement method has significantly increased the workload for engineers. In particular, the increasing complexity of tread patterns has led to a multiple increase in the time required for the arrangement, assembly, and quantity calculation of snow tire studs, resulting in a sharp rise in labor and time costs, severely restricting the overall efficiency of snow tire design work.

[0003] In existing technical solutions, manually arranging and calibrating the positions of the pins is not only time-consuming and laborious, but also prone to errors, especially when dealing with complex patterns and meeting strict regulatory requirements, where it is inefficient and difficult to guarantee accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for automatically arranging and inserting studs in tire tread patterns, which significantly improves design efficiency, reduces manual operation time and errors, accelerates the design process, optimizes the workflow, and improves design quality, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for automatically arranging and inserting studs in tire tread patterns, comprising the following steps: Construct a pitch position matrix A, preset the positions of the nails to be inserted in all pitches of the tire, and assign different colors to form a three-dimensional matrix containing pitch position, nail position, color and nail type; The pitch position matrix A is converted into a two-dimensional pitch pin distribution matrix B, which includes pitch position, pin position, and color; The drawing is read using the API provided by the drawing software, and a pitch color matrix C containing pitch position, nail position and color is generated. The corresponding elements in the pitch color matrix C are adjusted according to the pitch nail distribution matrix B. Based on the multi-color coding matrix, the elements in the cyclic pitch position matrix A are automatically matched with the elements in the pitch pin distribution matrix B and the pitch color matrix C according to the color and length attributes to find the position of the pin to be inserted and place the pin of the specified type.

[0006] Preferably, during the construction of the pitch position matrix A, for each nail position j at each pitch i, the corresponding color value k and nail type l are recorded to form matrix items [i,j]. k ,l].

[0007] Preferably, the method further includes: adjusting the color values ​​in the pitch color matrix C according to a predefined position and line color reference table.

[0008] Preferably, during automatic matching, the method further includes: using a WinForm user interface as the human-computer interaction interface, allowing users to input the name of the nail block and import the required nail arrangement table.

[0009] On the other hand, the present invention proposes a system for automatically arranging and inserting studs in tire tread patterns, comprising: The Pitch Position Matrix A building module is used to preset the positions of the nails to be inserted in all pitches of the tire and assign different colors to form a three-dimensional matrix; The conversion module is used to convert the pitch position matrix A into the pitch pin distribution matrix B; The drawing reading module is used to read drawing information using the API provided by the drawing software, generate a pitch color matrix C, and adjust it according to the pitch pin distribution matrix B; The intelligent matching and positioning module is used to automatically match the elements in the pitch pin distribution matrix B and the pitch color matrix C based on the multi-color encoding matrix and the elements in the cyclic pitch position matrix A set, to find the position of the pin to be set and place the pin of the specified type.

[0010] Preferably, the pitch position matrix A construction module supports custom nail types without requiring a preset correspondence.

[0011] Preferably, the intelligent matching and positioning module is also used to automatically check and ensure that the spacing and quantity of the nails meet the standards.

[0012] Technical effects and advantages of the present invention: The method and system for automatic arrangement and insertion of tire tread patterns proposed in this invention have the following advantages compared with the prior art: This invention constructs a pitch position matrix A and converts it into a two-dimensional pitch pin distribution matrix B. It then uses an API provided by drawing software to read the drawing and generate a pitch color matrix C. Finally, it adjusts the corresponding elements in the pitch color matrix C based on the pitch pin distribution matrix B. Based on a multi-color encoding matrix, by iterating through the elements in the pitch position matrix A, it automatically matches elements in the pitch pin distribution matrix B and the pitch color matrix C according to color and length attributes to find the pin's position and place the specified type of pin. This method significantly improves design efficiency, reduces manual operation time and errors, accelerates the design process, optimizes workflow, and enhances design quality. Attached Figure Description

[0013] Figure 1 This is a flowchart of the method for automatically arranging and inserting studs in tire tread patterns according to the present invention; Figure 2 This is a block diagram of the tire tread pattern automatic arrangement and stud system of the present invention. Figure 3 This is a schematic diagram of the drawing software calling principle of the present invention. Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] This invention provides, for example Figure 1 The method for automatically arranging and inserting studs in tire tread patterns, as shown, includes the following steps: Construct a pitch position matrix A by pre-setting the positions of the nails to be inserted in all pitches of the tire and assigning different colors, forming a three-dimensional matrix containing pitch position, nail position, color, and nail type; wherein, during the construction of the pitch position matrix A, for each nail position j in each pitch i, the corresponding color value k and nail type l are recorded to form matrix terms [i,j k ,l].

[0016] The pitch position matrix A is converted into a two-dimensional pitch peg distribution matrix B, which includes pitch position, peg position, and color. This step simplifies the original data structure and facilitates subsequent processing, as detailed below: Information extraction: From the original pitch position matrix A, for each element, extract three key pieces of information: "pitch position", "nail position", and "color". Here, "nail position and color" are combined (for example, a_50 represents the color value 50 at position a), and need to be parsed into independent "nail position" and "color".

[0017] Construct a new matrix: Use the extracted data of "pitch position", "nail position" and "color" to construct new entries. Each entry represents an element in the pitch nail distribution matrix B.

[0018] Ignore type information: When constructing the pitch pin distribution matrix B, there is no need to consider the "pin type" in the original matrix A, because it does not participate in the construction of the new matrix.

[0019] Let any element in the pitch position matrix A be represented as: ; Where: P i : The position of the pitch of the i-th nail; : A string combining the position and color of the nail; T i Nail type.

[0020] Will Break it down into nail position and color values: ; Where: L i : Nail location; C i Color value, represented by an integer.

[0021] Each element of the pitch-mounted pin distribution matrix B is constructed as follows: ; The final two-dimensional pitch pin distribution matrix B is: ; Where n represents the total number of nail positions in matrix A.

[0022] Through the above-described formulaic processing, the original three-dimensional pitch position matrix A is transformed into a two-dimensional pitch nail distribution matrix B containing only "pitch position, nail position, and color". This transformation retains key information and removes unnecessary nail type fields, facilitating subsequent automatic matching and positioning operations.

[0023] Using the API provided by drawing software (such as ZWCAD), the drawing is read to generate a pitch color matrix C containing pitch positions, nail positions, and colors. The corresponding elements in the pitch color matrix C are adjusted according to the pitch nail distribution matrix B, including: Initialize the data structure: Create an empty data structure (such as a list or dictionary) to store the information extracted from the drawing, namely the pitch color matrix C.

[0024] Using the API to read drawing information: This involves using the API provided by ZWCAD to read tire tread pattern design drawings. This typically involves opening the drawing file and iterating through the objects within it to obtain relevant information.

[0025] During the traversal, extract the joint position, nail position, and line color value for each object.

[0026] Constructing the pitch color matrix C: Based on the extracted information, construct an entry for each object, in the format [pitch position, nail position, color]. Add these entries to the previously created data structure to form the initial pitch color matrix C.

[0027] Adjusting matrix C based on pitch and pin distribution matrix B: Compare and synchronize the information in pitch and pin distribution matrix B with that in pitch and color matrix C. For each combination of pitch position and pin position existing in matrix B, find the corresponding element in matrix C and update it according to the color information in matrix B.

[0028] Ensure consistency: Use a predefined position and line color reference table to adjust the color values ​​in the pitch color matrix C to ensure color consistency and accuracy.

[0029] Based on the multi-color coding matrix, the elements in the cyclic pitch position matrix A are automatically matched with the elements in the pitch pin distribution matrix B and the pitch color matrix C according to the color and length attributes to find the position to be pinned and place the pin of the specified type. Specifically, the automatic matching process also includes: using the WinForm user interface as the human-computer interaction interface, allowing users to input the name of the nail block and import the required nail layout table.

[0030] Furthermore, the above method also includes: adjusting the color values ​​in the pitch color matrix C according to a predefined position and line color reference table to ensure color consistency and accuracy.

[0031] By automating processes to replace traditional manual layout and verification methods, significant time wasted on repetitive tasks was reduced. The introduction of a WinForm user-friendly interface allows users to set parameters and import data more intuitively, greatly simplifying the workflow, reducing learning costs, and improving the user experience.

[0032] In summary, this invention not only solves the problems of low efficiency and technical errors in existing technical solutions, but also significantly improves the design efficiency and quality of snow tires by introducing automation and intelligent methods.

[0033] On the other hand, this invention proposes a system for automatically arranging and inserting studs in tire tread patterns, such as... Figure 3 As shown, it includes: The Pitch Position Matrix A building module is used to preset the positions of the nails to be inserted in all pitches of the tire and assign different colors to form a three-dimensional matrix; furthermore, it also supports custom nail types without the need for preset correspondences.

[0034] The conversion module is used to convert the pitch position matrix A into the pitch pin distribution matrix B; The drawing reading module is used to read drawing information using the API provided by the drawing software, generate a pitch color matrix C, and adjust it according to the pitch pin distribution matrix B; The intelligent matching and positioning module is used to automatically match the elements in the pitch pin distribution matrix B and the pitch color matrix C based on the multi-color encoding matrix and the elements in the cyclic pitch position matrix A set, to find the position of the pin to be set and place the pin of the specified type.

[0035] Specifically, the intelligent matching and positioning module is also used to automatically check and ensure that the spacing and quantity of the nails meet the standards.

[0036] This system uses WinForms + ZWCAD for implementation. It obtains CAD drawing content and modifies related structures by calling the API interfaces provided by ZWCAD, such as... Figure 2 shown.

[0037] In addition, the modules mentioned above are also used to implement other steps of the method for automatically arranging and inserting tire tread patterns, as follows: 1. Construction of pitch position matrix A Pre-determine the positions of nails to be inserted in all pitches of the tire and assign different colors to them to form a three-dimensional matrix of pitch, all nail positions and colors, and nail types. The matrix is: [pitch position, nail position and color, nail type]. For example, if a nail of type b is placed at position a on pitch 1 and the line color of position a is 50, then the matrix is ​​[1, a_50, b].

[0038] 2. Pitch-mounted pin distribution matrix B transformation The tire pitch nail position distribution table is converted into a two-dimensional matrix containing the pitch and the position of the nail to be inserted. The matrix is: [pitch position, nail position and color]. For example, if a nail needs to be placed at position 'a' on pitch 1, then the matrix is ​​[1, a_50].

[0039] 3. Pitch Color Matrix C After the tire tread pattern is aligned circumferentially, the drawing is read using the API provided by ZWCAD to generate a three-dimensional matrix of pitch, position, and color. The matrix is: [pitch position, spike position, color]. For example, after the tire tread pattern is aligned circumferentially, if the line color at position 'a' on pitch 1 is 3, then the matrix is ​​represented as [1, a, 3].

[0040] Note: The nail type is user-defined and does not require a preset correspondence.

[0041] Position and line color reference table

[0042] The elements in the loop matrix A are automatically matched with the elements in matrices B and C based on attributes such as color and length of the lines. The position and type of nail to be placed are accurately located based on the provided distance, thus allowing the placement of the specified type of nail.

[0043] This embodiment uses a multi-color coding matrix to change the traditional method that requires 20-30 minutes of manual setup for a single drawing, plus 5 minutes of proofreading. This method can achieve setup in 15 minutes without proofreading, improving work efficiency by 50% and increasing work accuracy. At the same time, it meets the mandatory requirements of ECE R117 regulations on the spacing and number of pins.

[0044] Note: Comparison table of old and new plans

[0045] In summary, this invention constructs a pitch position matrix A and converts it into a two-dimensional pitch pin distribution matrix B. It then uses an API provided by drawing software to read the drawing and generate a pitch color matrix C. Finally, it adjusts the corresponding elements in the pitch color matrix C based on the pitch pin distribution matrix B. Based on a multi-color encoding matrix, by iterating through the elements in the pitch position matrix A set, it automatically matches elements in the pitch pin distribution matrix B and the pitch color matrix C according to color and length attributes to find the position of the pin to be placed and place the pin of the specified type. This method significantly improves design efficiency, reduces manual operation time and errors, accelerates the design process, optimizes the workflow, and enhances design quality.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
